Studies Show Bad Teeth Are Not Because Of The Genes But Because Of Nutrition
People with bad teeth are themselves to blame for this by wrong food and too little care. According to researchers, genes hardly play a role.
American researchers conclude that.
“Limiting sugar consumption and acid buildup in the mouth has long been the dogma of the dental community,” says senior researcher Karen Nelson in the journal Cell Host & Microbe. “This research introduces specific bacteria groups that can grow through the environment causing holes.”
Since a century it has been known that streptococcus cause cavities, because they affect the enamel of the teeth. The researchers compared the dentures of 280 two-person and 205 identical twins between 5 and 11 years old. It showed that the type of bacteria in a mouth is genetically determined, but that it has little influence on cavity formation.
The children in the study who ate a lot of sugar had a lot of bacteria in their mouths that cause tooth decay. And children who ate little sugar hardly possessed it. The influence of brushing on the teeth was not included in this study, but the scientists continue to follow the twins.
